| - ---++Example for querying the SPARQL-SSL endpoint using Virtuoso function http_client
The following example demonstrates how to query the SPARQL-SSL endpoint (listening on default HTTPS 443 port) using Virtuoso function http_client:
1 Make sure the steps from the [[VirtSPARQLSSL][FOAF+SSL cURL Usage Guide]] are done.
1. Log in at Virtuos ISQL with your user credentials:
<verbatim>
C:\>isql localhost:1111 johndoe ****
Connected to OpenLink Virtuoso
Driver: 06.01.3127 OpenLink Virtuoso ODBC Driver
OpenLink Interactive SQL (Virtuoso), version 0.9849b.
Type HELP; for help and EXIT; to exit.
SQL>
</verbatim>
1. Execute:
<verbatim>
SQL>select http_client ('https://localhost/sparql-ssl?query=select+*+where+{+%3Fx+%3Fy+%3Fz+.+}+limit+10&format=text%2Fn3', cert_file=>'d
b:cli_key', insecure=>1);
